Pouring concrete in a basement

[Aaron J Latal]

Hello all! I am looking into buying an old 2 family unit and turning it into a 3 bedroom single family unit.  The property needs a lot of work done which is perfect, I can make it look exactly how I want it.  There is one part of this project that has me stumped on rehab estimates though, the basement. The basement needs to be finished... there is no concrete floor, just dirt.  The house is in St. Louis city and as many old houses in the city it has limestone blocks for a foundation which seems to be in good shape but no concrete floor.  The square foot area of the basement is about 900 and about 1/3 of it has concrete but I am wondering if anyone has an idea of what it would cost to put concrete into this basement as the first step towards finishing it? Thanks in advance for any help or suggestions!
